A US woman who shot and killed her husband and two adult children before taking her own life is thought to have committed the shocking crime as a result of being ostracised from the religion she was raised in.

Every time I tell a mate I’m doing a story on cryptocurrency, they invariably ask me the same two questions: should they invest their own hard-earned money, and which cryptocurrency will get them a Lamborghini/yacht/island quickest?

Libs accused of being too fond of Israel

Supporters of Palestine in Perth say Liberal politicians are biased in favour of Israel.

They say the Liberals are willing to attend events organised by Zionists but never accept invitations to Palestinian events.

Liberal MP Ian Britza, acting as a representative of WA Premier Colin Barnett, attended a State Zionist Council rally in Perth on Sunday as Israel continued to trade hostilities with Palestinian forces.

Friends of Palestine WA co-convenor Alex Whisson says Liberal politicians have been invited to his group's events but have never accepted.

"It does say something about political allegiances, certainly of the Liberal government, that they would accept an invitation from the Zionists," Mr Whisson told AAP on Monday.

"Both major parties feel it's incumbent on them to provide uncritical support to the state of Israel, simply because of our alliance with the United States.

"It behoves us as a nation to pursue independent foreign policy, which is committed to the principles of justice and peace, and condemns what is wanton violence against civilian property and civilian lives in Gaza."
